kandi X-RAY | magnolia Summary
Magnolia is a generic macro for automatic materialization of typeclasses for datatypes composed from product types (e.g. case classes) and coproduct types (e.g. enums). It supports recursively-defined datatypes out-of-the-box, and incurs no significant time-penalty during compilation.

QUESTION
I am trying to use OSGI to allow me to use two different versions of a transitive dependency. The plan is that one version (the newer version) will be hidden away inside an OSGI bundle, the other will be on the runtime classpath as normal.
I have built the bundle jar using Gradle (with the Groovy DSL), but the problem is its associated runtime dependencies are wrong - it brings along the newer version, which is supposed to be hidden inside the bundle. This is still true when I do, in the build.gradle
file:
ANSWER
Answered 2021-May-05 at 20:46From the Gradle documentation:
On the upside, Gradle’s exclude handling is, in contrast to Maven, taking the whole dependency graph into account. So if there are multiple dependencies on a library, excludes are only exercised if all dependencies agree on them. For example, if we add opencsv as another dependency to our project above, which also depends on commons-beanutils, commons-collection is no longer excluded as opencsv itself does not exclude it.
So instead, we can use a dependency resolve rule:

following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
SparkNotes:
I'm pulling in a crime API to see hotspots. Certain crimes will not be logged with a lat/long, therefore, are not shown up in standard (free) crime apps.
- Lat/Long pins I've overridden to a new lat/long don't show up on first load/or at all. (google-maps-react) (Confirmed lat/long is valid per crimes in near areas.)
- Normal pins that had an existing lat/long show up fine/show up as soon as it loads. (Even though it's all the same array of data.)
- I loop through the blank lat/long and replace the lat/long with a rough lat/long of the area just so it shows up. In my console log I can confirm that I've overriden the blank lat/long.
- I want these records to understand the neighborhoods/potentially avoid moving into a hotspot of specific crimes.
API Normal:
https://data.seattle.gov/resource/tazs-3rd5.json?$limit=20000&$offset=20000&$order=offense_id
Full Use Case (Which doesn't work for at all pins): https://data.seattle.gov/resource/tazs-3rd5.json?crime_against_category=PERSON&mcpp=MAGNOLIA&offense_parent_group=SEX%20OFFENSES
Request for help: Can someone please help on how to get these overridden pins to show up consistently?
Things I've Tried: Force update/having multiple refreshes etc/decreasing async time. Those work for when I put in specific crime report number, but if I search for kidnapping/peeping tom, they will not pull with the rest of the person crimes.
I can confirm that if I just load every crime in that API, the map logs all of them (except the ones I need), It's like a pin per foot of street, but the pins in the categories I need don't show up. (So I don't believe it's a volume issue.)
Code for API Data:
...ANSWER
Answered 2021-Apr-27 at 03:04It seems that there's a timing issue when importing your places
data from crimedata.js
in the first load of the code. I can see that the places
value is empty [] in the initial run then the loading of your places in your crimedata.js
will follow after some time. You can see this in the console log in my working code.
To handle this, I used state variables to hold the value of the updatedPlaces
data then in componentDidMount
function, I used setTimeOut and set value of updatedPlaces
state variable from the imported places data that is now available.
I then used this state variable as a condition for the markers to load.
Here's the code snippet:
QUESTION
We need to load static UI pages in iOS native App using Magnolia REST API JSON. Is there any SDK to work with that JSON? I searched every possible thing but got nothing. Any leads or help will be appreciated.
...ANSWER
Answered 2021-Apr-12 at 07:02For basic usage there is no SDK - you can use standard Swift teqniques to hit a REST endpoint with the Magnolia endpoints.
Some examples https://docs.magnolia-cms.com/product-docs/Getting-started-with-Magnolia/Getting-started-with-REST.html
Endpoint Documentation https://docs.magnolia-cms.com/product-docs/Developing/API/REST-API/Delivery-endpoint-API/Delivery-endpoint-API-v2.html
For more advanced usage with React, Angular or Vue, Magnolia does have SDKs. That is described here: https://hd.magnolia-cms.com/docs/getting-started/hello-spa

placeholder.yaml:

QUESTION
In the example for the magnolia module configuration in the documentation I am not sure why the private boolean colorsEnabled;
for the FooBar class is not in the YAML configuration. Where does the module configuration get the colorsEnabled
property from?
ANSWER
Answered 2021-Mar-04 at 13:37FooBar class is not in the YAML configuration. Where does the module configuration get the colorsEnabled property from?
First YAML/FS is checked, then from the JCR configuration (config
workspace in the repo). Or if property of that name doesn't exist it would take the default value.
More on the order in which resources are checked here.
The list appears to be always null.
yes, because you override the value from yaml with the one in config workspace (or you have just one in the workspace and nothing in yaml?) and there you still write the property list in yaml format instead of using syntax appropriate for jcr (which would be contentNode
called excludes
with 4 properties under that node each being name/value pair representing the individual colors. Unfortunately documentation doesn't show how that differs so clearly so it's easy to make a mistake there.
Anyway, as a good practice you should choose where you will store your configuration - either in repo or in yaml. I would suggest yaml config in FS as it allows you to change the configuration from outside even if your app gets corrupted. Plus it's easier to keep that file in git or other VCS and have proper history of changes on it tracked.
QUESTION
I need to understand under what conditions is a module configuration file loaded from the FileSystem (FS). Specifically I would like to know why is config.yaml file not loaded in the configuration?
Here is my src/main/resources//config.yaml
according to the file module structure described here and here.
ANSWER
Answered 2021-Mar-05 at 10:09I think it is because you are checking the wrong documentation. Please refer to 5.7 documentation from https://documentation.magnolia-cms.com/display/DOCS57/
If I recall correctly, the feature is implemented from the 6.1 version.
And the page you are looking for is the following: https://documentation.magnolia-cms.com/display/DOCS57/Module+configuration#Moduleconfiguration-ConfiguringinJCRvsYAML
Notice the bean definition there.
